Meta's Ads Manager gives you somewhere north of 200 metrics to look at. Most of them are noise. A small number actually tell you something useful. Here's the list.
The Metrics That Matter
Cost per result
Cost per lead (for lead generation campaigns) or cost per purchase (for conversion campaigns). This is the headline number: what are you paying for the outcome you're actually trying to achieve? Track it weekly against your target CPL or CPA and compare it to the previous period.
ROAS or CPL against your benchmark
Return on ad spend for ecommerce. Cost per lead against your acceptable acquisition threshold for lead gen. These numbers are only meaningful when compared to something: your historical average, your target, or a period when the account was performing the way you want it to.
Link click-through rate
The percentage of people who saw your ad and clicked the link to your website (not just any click on the post). This is your creative effectiveness signal. A drop in link CTR, all else equal, means your creative is losing its ability to generate interest. Meta benchmarks vary by industry, but a consistent decline over time is the signal to watch.
Landing page conversion rate
What percentage of people who clicked your ad actually converted? This lives in GA4 or your CRM, not in Meta. If your link CTR is fine but your CPL is rising, the problem is often on the landing page, not in the ad. This metric connects Meta's performance to what happens after the click.
Frequency
How many times on average has someone in your audience seen your ad. Once frequency starts climbing above 3–4 for a cold audience, you're likely seeing the early signs of creative fatigue. CPL goes up, CTR goes down, and the ads stop working not because the targeting is wrong but because the same people have seen the same creative too many times.
Hook rate and hold rate (for video)
Hook rate: what percentage of people watched at least three seconds. Hold rate: what percentage watched to 25% or 50% of the video. These tell you whether your video is arresting attention (hook rate) and whether the content sustains it (hold rate). Low hook rate = the first frame isn't stopping the scroll. Low hold rate = people aren't interested after the initial hook.
The Metrics That Look Important But Usually Aren't
Reach and impressions
How many people saw your ad. Useful as context, not as a success metric. Reach and impressions go up when you spend more. They tell you nothing about whether the right people are seeing it or whether any of them are taking action.
Relevance score
Meta deprecated the original relevance score and replaced it with three sub-scores (quality ranking, engagement rate ranking, conversion rate ranking). These are directionally useful for diagnosis but shouldn't be used as primary performance indicators. A campaign can have a below-average engagement rate ranking and still have an excellent CPL if the targeting is right.
Post engagement
Likes, comments, shares, reactions. These are brand awareness proxies, not lead or revenue drivers. High engagement on an ad that doesn't convert is just an expensive vanity metric. The exception: if you're explicitly running an engagement objective and using those audiences for retargeting.
CPC (all)
This includes all clicks: on the ad image, on your page name, on the "see more" button. It dilutes the signal from the metric you actually care about, which is link CTR and cost per link click. Use cost per link click, not CPC all.
CPM
Cost per thousand impressions. Useful for understanding how competitive your auction environment is, but not for evaluating campaign performance. A high CPM with great targeting and strong creative can produce better results than a low CPM with broad audiences and weak creative.
The One Table to Build
If you build a weekly reporting table, include five columns: Spend, Link CTR, Cost per result, Frequency, and ROAS (or CPL against target).
Those five columns tell you almost everything you need to know about whether a campaign is working, why it might be underperforming, and where to focus attention next.
One Thing Meta's Dashboard Can't Tell You
Lead quality. Meta tracks leads generated; it doesn't know which ones became customers. The most important metric for a lead generation account, close rate and cost per acquisition, lives in your CRM, not in Ads Manager.
Build the habit of connecting Meta data to CRM data at least monthly. It's the only way to know whether your campaign's CPL is actually producing value, or just volume.
Frequently Asked Questions
What's a good link CTR for Meta Ads?
It varies significantly by industry, format, and objective. Cold traffic campaigns often see link CTRs in the 0.5–1.5% range. Warm retargeting can be 2–4%+. What matters most is the trend in your own account. Consistent decline is the signal, not whether you're above or below an industry benchmark.
Our frequency is at 6 but our CPL is still good. Should we still refresh creative?
If your CPL is stable, you don't need to refresh yet. Frequency is a leading indicator of fatigue, not a direct cause of it. Watch your week-over-week CPL. If it starts trending upward as frequency climbs, that's the signal to act.
Should we be in Ads Manager every day?
No. Daily changes disrupt the learning phase and make it harder to interpret performance data. A weekly review cadence (checking the five columns above, making one or two considered changes based on the data) is better practice than daily adjustments.
